MACHINE FOR MAKING TAPE TRIlVIlVIING.

Specification of Letters Patent No. 32,663, dated .Tune 25, 1861.

f7o all whom 'it may concern:

.Be it known that I, JOHN E. EARLE, of Brooklyn, in the county of Kingsand State of New York, have invented a new and useful Machine for MakingTrimming from Tape or other Ribbon, and commonly called Tape Trimming; 2and I do hereby declare that the following' is a full, clear, and exactdescription of the construction and operation thereof, reference beinghad to the accompanying drawings, making a part of this specification,in which- Figure l is a perspective view. Fig. 2 is a sectional view.Figs. 3, 4L, 5, 6, 7, show the manner of laying the five folds requiredin making the particular kind of trimming for which this machine isadapted. Figs. 8, and 9, represent detached parts of the machine.

Same letters and characters refer to like parts.

The nature of my invention consists, first, in folding the tape or otherribbon by means of pincers or folders formed of 'plates or wires or bothor their equivalents, so arranged as at the right moment to move in to,(the tape being in or near the center around which the folders areplaced,) and clasp the tape, and by a whole or partial revolution of thefolders to fold the tape to the required form or angle, thenwithdrawing, when a second pair of folders in like manner as the firstenters and lays the second fold and withdraws, and the successivefolders continuing so to do until all the required fo-lds are laid andthe web of the tape brought back to place of beginning; secondly, in adevice for untwisting the tape (twist being caused by laying two foldsin one direction and three folds in opposite direction making a twist inthe tape of one half round,) by means of a continuous revolution givento the holder upon which the tape (from which the trimming is to bemade) is placed turning it in the' direction to accomplish the resultrequired; thirdly, in a device for carrying the tape from the lastfolders into the position required to receive the first folders, andretaining the tape in said position until the first folders or pncershave entered and taken hold of the tape,

having its bearing in the bracket Y Fig. 2; I the spool; L the tape orother ribbon; M spur gear through which a revolving motion is given tothe holder H by means of the gear R on the edge of the `disk S throughthe pinion N and O on the shaft P.

Operation: In Figs. 3, 4, 5, 6, 7 the folders are shown in black when atrest, red when they are in position to fold, and blue when they havefolded. The tape is shown in black before the fold is made, and yellowafter the fold is made. When the machine is in motion the folder D, Fig.8, by means of the action of the cam P acting through the rod O andlever M is moved into the position denoted by the red lines, the wire 1passing above and the plate 2 below the tape L, (the holder C stillretaining the tape in position 3); when arrived at this position thefolder revolves by the action of the cam B through the agency of the rodA and levers WV and U, at the same time the holder C through itsconnection H2 and I2, Fig. 9, with the said lever IV( operating thefolder D is raised from its position A3 to B3 and allows the tape toclear from its point the folder D turning until it attains the posit-iondenoted by the blue lines and carrying the tape from position 3 to theposition 4L shown by the yellow lines. During this operation the secondpair of folders E enters in the same manner as the first pair D and whenat or about the position denoted by the dotted lines in Fig. 3 the firstpair D withdraws and returns to the position of rest denoted by theblack lines, and the second pair of folders continues to enter until theposition denoted by the red lines Fig. l is reached, the plate 1 beingabove and the plate 2 below the tape (this folder is composed of twoplates so that they may hold the fold already made by the firstoperation) and in the same manner as the first turn to the positiondenoted by blue lines, carrying the tape from position 4- (in blacklines) to position 5 in yellow lines, the folder E remaining in thisposition until the third folder F enters to the position denoted by thered lines (the wire 1 being above and the plate 2 being below the tape)when the second folder E withdraws to first position shown in blacklines Fig. 3. The third folders F turning in like manner as the firstand second before described to the position denoted by the blue linesFig. 5, carrying the tape from position 5 (in black lines) to position 6(in yellow lines) the folders F remain in this position until'the fourthfolders G enter to the position denoted by the red lines Fig. 5, whenthe third folder F withdraws to first position denoted by black linesFig. 4. The fourth folder G turning in the manner of the first folderbefore described to the position denoted by the blue lines, Fig. 6carries the tape from position G in black lines to position 7 in yellowlines. As in this position the fifth folder H cannot enter, the pressersE and F (being in position denoted by red lines Fig. 2) are by theaction of cam S closed upon the tape and folders G and holding fast thetape, the folders G withdraw to first position denoted by black lines,then the fifth and last folders H enter to the position denoted by redlines Fig. 7 (the wire l being below and the plate 2 above the tape) andturns in like manner as the first before described, down and under tothe position denoted by blue lines carrying the tape from position 7 toposition 8 being the position first denoted at 3 in Fig. 3. The carrierD on the spindle I of folder H carries the tape down and around to theholder C then withdrawing leaves the tape in the first describedposition so as to receive the first folder D commencing anotheroperation.

As in folding the tape there are three folds in one direction and two inthe reverse, there is a consequent twisting of the tape, one half aroundwhen the five folds are completed, and the tape would so continue totwist at each full operation. To overcome this continuous twisting thespool holder H is made to revolve one half around (in the direction toobtain the required untwisting) during each full operation by means ofthe gears M and R and the pinions N and O thus leaving the tapeuntwisted at the close of each full operation.

As the trimming X is formed in the nianner before described, it iscarried through the trough or guide G to the sewing 1nachine or otherknown device for fastening the folds so as to retain them in place foruse.

Power may be applied to the driving shaft R.

I do not confine myself to this one particular description of trimmingherein described as the several folders may be adjusted so as to fold invarious forms. Neither do I confine myself to the precise constructionherein described, reserving to myself the right to modify, so long as Ido not depart from the general principles herein set forth.

Having thus fully described my invention what I claim therein as new,and useful, and desire to secure by Letters Patent is,

l. The folders D, E, F, G, and H, or their equivalents constructed andoperating in the manner and for the purpose substantially as specified.

2.
